Disadvantages of noninvasive ventilation include which one of the following?
A. costs more than invasive ventilation
B. requires heavy patient sedation
C. limits direct access to lower airway
D. increases the likelihood of V AP - ANS Disadvantages of noninvasive
ventilation (NPPV) include the following: it can only be
used in cooperative patients; it does not provide direct airway access (thus
increasing
the risk of secretion retention), and more therapist time is needed during the
initial
period of use. On the other hand NPPV may help decrease the incidence of V AP
and
typically costs less than invasive ventilation.
The correct answer is: limits direct access to lower airway
On a patient receiving volume control AC ventilation, you observe a flow-volume
with a sawtooth pattern on exhalation. Which of the following actions would you
consider most appropriate?
A. recommend administering a bronchodilator B. assess the patient's need for suctioning
C. measure the endotracheal tube cuff pressure
D. switch to pressure control ventilation - ANS The flow-volume loop reveals
irregular sawtooth- like oscillations, primarily in the
expiratory portion of the loop. This indicates either 1) accumulation of airway
secretions in the trachea/large airways (requiring suctioning), or 2) condensate
partially
blocking the expiratory limb of the ventilator circuit proximal to the expiratory
flow
sensor . Auscultation of rhonchi or tactile fremitus over the trachea would confirm
excess secretions as the problem.
The correct answer is: assess the patient's need for suctioning
A 30 year-old male was found supine and unresponsive. In the ER it was
confirmed he had aspirated while on his back. After the patient is transferred to
ICU his physician orders postural drainage and percussion every 4 hours. What is
the best position to place him in to drain the affected area?
A. prone with a pillow under his hips
B. prone with feet elevated 30 degrees
C. supine with a pillow under his hips
D. supine with feet elevated 30 degrees - ANS This patient aspirated while lying
flat on his back. Most commonly , this affects the superior segments of both lower lobes. The position which facilitates drainage
from
this lung region is a prone position with a pillow under the patient's hips.
The correct answer is: prone with a pillow under his hips
You need to perform nasotracheal suctioning on a patient with retained
secretions. As compared to suctioning via a tracheal airway , which of the
following complications are unique to this procedure?
A. hypotension
B. gagging/aspiration
C. hypoxemia
D. increased ICP - ANS Complication/hazards common to both
tracheobronchial and nasotracheal suctioning
include hypoxemia, cardiac dysrhythmias, bradycardia, hyper-/hypotension,
bronchospasm, atelectasis, increased intracranial pressure and the potential for
contamination/infection. Unique complications of nasotracheal suctioning
include
nasal trauma/epistaxis, pharyngeal trauma, gagging (with potential
241
vomiting/aspiration), and laryngospasm. Also misdirection of the catheter is more
common with nasotracheal suctioning.
Which of the following indicates a deficit in fluid balance A. Pedal edema
B. Poor skin turgor
C. cap refill
D. JVD - ANS Poor skin turgor
ARDS patient, what should RT use to evaluate oxygen delivery for optimal PEEP
A. ABG
B. mixed venous
C. serum lactate
D. CO - ANS mixed venous
RT performing a high calibration on a nitric oxide, expected value is
A. 45
B. 10
C. 25
D. 80 - ANS 45
To help prevent infection after an aerosol drug treatment provided via small
volume nebulizer (SVN) you would:
A. shake out any residual solution then bag the SVN
B. rinse the SVN with tap water then dry and bag it
C. run the SVN at high flows until completely dry
